A variety of inositol phosphates including myo-inositol 1,4,5-trisphosphate, which is a secondary messenger in transmembrane signaling, were selectively synthesized via Yb(OTf)3-catalyzed desymmetrization of myo-inositol 1,3,5-orthoformate using a proline-based chiral anhydride as an acylation precursor. The investigated catalytic system could regioselectively differentiate the enantiotopic hydroxy
各种肌醇磷酸酯,包括肌肉肌醇1,4,5-三磷酸,它是在跨膜信号传导的第二信使,经由被镱(OTF)选择性地合成3的催化的desymmetrization肌醇肌醇1,3,5-使用原甲酸酯脯氨酸基手性酸酐作为酰化前体。所研究的催化系统可以区分区域选择性的对映羟基肌肉中的手性助剂的存在肌醇1,3,5-原甲酸酯。这个关键步骤,以产生适当保护的手性肌醇肌醇衍生物在这里被描述为一种统一的方式来肌醇磷酸酯的访问。
